| Zusammenfassung: | Title screen The luminescence of Li2O–B2O3–P2O5–CaF2 glass doped with Tb3 +/Eu3 + under electron beam excitation have been investigated in detail. The excitation spectra, photoluminescence (PL), pulse cathodoluminescence (PCL) and luminescence decay kinetics were analyzed. The energy transfer efficiency from Tb3 + to Eu3 + ions was found to increase at increased concentration of Eu3 + ions. As the concentration of europium grew, the luminescence quenching was observed. The energy transfer from Tb3 + to Eu3 + was observed to occur through level 5D4 of terbium ions. It is shown that the luminescence decay kinetics of terbium ions at 485, 544, 622 and 700 nm depends on europium concentration. Режим доступа: по договору с организацией-держателем ресурса |
